in. 918,603. I i Application filed April To all whom it may concern:

Creeping of Railwoylioils, and declare the following to be a full,clear, and exact (lescription of the some, such as will enable othersskiliied in the art to which it pertains to make end use the some,reference being: lied to theaccompanying drawings, which. form a part ofthis specification.

My invention has for its object to provide a. simple and novel devicefor preventing rails from creeping.

The Various features of novelty whereby my invention is characterizedwillv be hereinafter pointed out with particularity in the claims, butfor a'full llnderstnnding of my invention and its object and advantagesreference may be had to the following detailed description taken inconnection with the sccompanying (l rowing, w herein:

Figure 1 is a plan "View of e preferred form of my invention showing itportion of a rail way tie and in dotted ines a railway rail; Fig. 2 isan end View of the device shown in Fig. 1, the mil lie-ingshownin'section; and.

Figs. 3 and at are views similar to Fig. 'i showiog furthermodifications.

; Referring to Figs. 1 and 2 ot the drawing and B represent apanr ofarms having upturned over-hanging; flanges a and b at their outer'cnds.The members A and B are piv" otelly connected together at C. One of themembers is continued beyond the pivotal point as at A so as to provideon anchoring: arm. The distances between the flanges o and l) and thepivotal. connection is such thetwhen the device is placed beneath thebase of a rail and the flanges o and b are made to engage with the sidesthereof, the pivotal point will lie at one sideof a line drawn transversely of the rail and passing through the flanges a and I). By thisarrangement. if the anchoring arm is securely held then :1 tendency onthe part of the rail U1 creep for-- wordly, that is in the directionfrom the pivotal point of the members towonl their outer ends, will drawthe two clamping jaws toward each other and into more intimatecoutoet'with the rail, in the manner thot the weight of the bloc 1 olivecauses the ire tongs to tighten their grip.

In applying the device, it is placed under Specification of LettersPatent.

While I have described in detail a few preferred forms ofmy invention Ido not desire to be limited to the exact construction and arrangement ofparts shown, since in its broader aspects my invention may takevariousother forms as will be evident from the terms employed in thedefinitions thereof constituting the'a pended claims.

Having now ful y described my invention, What I claim as new and desireto secure by Letters Patent is 1 A device of the character described comrising a air of jaws arranged to underlie t e base oi rail and=pivotedtogether at a point beneath the rail, and an anchoring one of saidmembers in the rear of the pivot.

In a device of the character described, a pair of pivot-allyconnected. members adapted to be arranged beneath the base of a raid infront of a tie, jaws arranged on the endsof said members in front of thepivotal point and shaped to grasp the edges of rail base, and ananchoring arm GXtGIlClIlHQfIOIH one of said members to the tie.
